Partitioned Power Storage Module With Isolated Cooling Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power storage modules face challenges in efficiently cooling multiple electrode assemblies housed in separate compartments, as heat generated in one compartment can easily be transmitted to others through partitions, leading to inefficient cooling.
Innovation Solution
A power storage module design featuring a case with partitioned compartments and dedicated cooling paths for each compartment, where the first and second cooling paths are strategically positioned to isolate and efficiently cool the electrode assemblies, reducing heat transfer between compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If partitions are used to separate electrode assemblies into compartments, then spatial organization and safety are improved, but heat transmission between compartments increases
Solution Approach 1:
The cooling system is segmented into multiple independent cooling paths, with each cooling path dedicated to a specific compartment. This segmentation prevents heat from transmitting between compartments while maintaining effective cooling for each electrode assembly independently.
Solution Approach 2:
The partition structure serves as a thermal barrier (intermediary) between compartments, and the dedicated cooling paths act as mediators to remove heat from each compartment separately, preventing heat transmission while maintaining compartment separation.
2Productivity
If dedicated cooling paths are provided for each compartment, then cooling efficiency is improved, but device complexity increases
Solution Approach 1:
The case body is designed to serve multiple functions: it provides structural support, creates compartment separation through partitions, and simultaneously forms the cooling paths within its structure. This multi-functionality achieves dedicated cooling for each compartment without proportionally increasing device complexity.
Solution Approach 2:
The cooling paths are merged into the case body structure itself rather than being separate components. The case body integrates both the partitioning function and the cooling path function, reducing overall device complexity while maintaining dedicated cooling efficiency.

AI summary
A power storage module has a case (200) including a case body (210) and at least one partition portion (220). The case body (210) surrounds a plurality of electrode assemblies (100). The partition portion (220) is located between the electrode assemblies (100) adjacent to each other to partition an accommodation space (S) of the case body (210). In the accommodation space (S) of the case body (210), the partition portion (220) forms a first compartment (S1) and a second compartment (S2) adjacent to the first compartment (S1) with the partition portion (220) interposed between the first compartment (S1) and the second compartment (S2). A first cooling path (500) and a second cooling path (600) are formed in the case (200), the first cooling path (500) extends in a portion of the case (200) that faces the first compartment (S1) without the second compartment (S2) in between, and the second cooling path (600) extends in a portion of the case (200) that faces the second compartment (S2) without the first compartment (S1) in between.
